Anatomical Studies of Sphaeropteris and Cnemidaria (Cyatheaceae)
American Fern Journal, 1985 Tryon (1970) revised the classification of the family Cyatheaceae and recognized six genera and three principal evolutionary lines among the squamate genera. Sphaeropteris with its undifferentiated (conform) scales represents an evolutionary line and occurs at the base of the squamate genera, while Cnemidaria with its marginate scales is found at the ...

Ontogeny of the Sporangia of Sphaeropteris cooperi
American Fern Journal, 1999 -The ontogeny of the sporangia of Sphaeropteris cooperi was studied using cleared whole mounts of sporangia in different stages as well as sori embedded in paraffin and sectioned. The sporangia develop from a single superficial primordial cell that becomes divided into five initials or "segments." Segment 0, located at the level of the surface ...

Morphology of Gametophytes and Young Sporophytes of Sphaeropteris lepifera
American Fern Journal, 2000 -Sphaeropteris lepifera is one of the largest tree ferns in Taiwan. On average, it produces 50.7 sporangia per sorus, and 64 spores per sporangium. Spore germination, after 2 years of storage at 4?C was over 95%. The pattern of spore germination was "Cyathea-type", and the gametophytes exhibited mainly Drynaria-type development with occasional Adiantum-

The Tree Fern Highland Lace is a Cultivar of Sphaeropteris cooperi
American Fern Journal, 2012 The tree fern Highland Lace had an unusual introduction into cultivation almost thirty years ago in Eastern Australia and was initially identified as Sphaeropteris tomentosissima (Copel.) R.M.Tryon. Since then, it has been introduced to Europe and the US,

Annals of the Missouri Botanical Garden, 1979 Two previously unidentified palynomorphs are common in Upper Tertiary deposits in the southern Gulf-Caribbean region. One is now identified as pollen of Mortoniodendron (Tiliaceae; Upper Miocene of Veracruz, Mexico, Middle Miocene of Panama, Pleistocene of Panama). The other represents spores of Sphaeropteris/Trichipteris (Cyatheaceae; Upper Miocene of

In this study, we analyzed the genetic structure and phylogeography of Sphaeropteris brunoniana from China and Laos. Combining cpDNA trnL-trnF and atpB-rbcL sequence variations, five haplotypes were identified from the 10 investigated populations. Moderate haplotype diversity (h = 0.66580) and low nucleotide diversity (pi = 0.23 x 10(-3)) were detected.

During the first 96 h of culture, germinating spores of the fern Sphaeropteris cooperi (F. v. Muell.) Tryon showed a gradual rise in respiratory activity to a maximum of about 6.5 μl 02 h−1 mg−1 dry wt. This was followed by a transitory decline in rate, concluded by a second respiratory rise preceding the emergence of the rhizoid after 192 h of culture.
